Business Insider reports Nick Kyrgios trolled rivals Novak Djokovic and Rafael Nadal during a podcast interview with a prominent tennis journalist. Kyrgios called Djokovic "cringeworthy" because of the way he celebrates, and said Nadal is "salty." All three athletes are competing in this week's Italian Open, as they prepare for the highly-anticipated French Open at Roland Garros later in the month. Kyrgios could meet Djokovic in the Italian Open quarterfinal if both players continue to win.
